I ended up telling them the same thing and ordered 2 extra screws as well. They were a pain in the *** to line up, but worth the frustration.That happend when i placed my order with my vin number they replied saying that my truck didnt came with that parts from factory so i just replied that it was for a custom-built you should be fine just check the number of screws you need may vary if you dont have fender flares.
These liners are for the 19-20 DT (5th Gen)
